To all 'whom t may concern:

Be it known that l, FELIX KIRSCHNER,

e 72, Republic of Austria, have invented ceru tainnew and useful improvements in Apparatus for Electrogalvanizing, of which the following-is a specification.

lit has already been proposed to use apparatus for electrogalvanizing in which the articles to be galvanized hang motionless in an electrolyte which is kept. in motion, and also to use baths in which the articles to be galvanized are kept in motion whilst the electrolyte is either motionless or kept in motion. llllectrogalvanizing devices are also known in which a circulation of the electrolyte is eii'ected by means of heating devices. W ith these baths, however, when the articles travel through them very rapidly and high currents are employed, a high quality galvanization cannot be relied upon with certainty. ln the galvianization of wire, stripl iron and the like upon a large scale it is very important to secure a high quality of galvanization with reliability and rapidity not only for economical reasons but also upon technical grounds.

ln the rapid gaivanizing of wires, strip iron and the like upon a large scale the goods to be galvanized must be treated in e continuous operation both bei'ore and after galvanizing. This necessitates great efficiency and certainty of operation o' the galvanic bath by reason of the great speed at which the articles travel through the bath, particularly where a heavy galvanic coating ot metal is to be applied. Besides this, the speed of operation of the apparatus for the preliminary and subsequent treatnient can easily be increased, whilst the electrogalvanizing process itself, according to methods hitherto known, cannot be made to keep pace with the increased speed ot l operation of this apparatus.

rlhe problem of the rapid galvanizing of articles traveling rapidly through the4 galvanizing bath is solved according to the prese-nt invention by roviding the bath with a trough prefera ly in the form of a gutter to which are connected one or more circulating channels or conduits of' special construction in which are arranged devices such as propellers, for example, for producing an energetic current in the electrolyte in a direction opposite to that of the traveling goods. f

lin the accompanying drawings the invention is illust-rated in one form of construction.

Figs. 3 and 4 show the right hand end of the apparatus on a larger scale in sectional elevation and plan respectively.

Figs. 5 and 6 show the left hand endof the apparatus, on the saine scale as Figs.

Fig, 7 is a section on the line Vil-Will of Fig. 3.

Fig. 8 is a section of line VHl--Vlllll of Fig. 3.

Figs. 9 and l0 show details on a still larger scale in sectional side view and end elevation.

The bath consists ot a narrow, shallow and comparatively long gutter-shaped trough l. ltollers 2 and 3 are provided for guiding les :c travel o" through the bath.

Fihrough the rising pipe l2, in the construction illustrated in the drawings, there passes an auxiliary pipe 13, which is supplied with steam or hot water. At the end of the auxiliary pipe 13 is provided a condenser la. Vlline heating of the circulating conduit l0 can be etlected in other ways. rThe right hand end of the trough is provided with a lateral extension l5 Fig. 7) at the bottom of which is inserte the union with the down pipe l. ln the down pipe 11 is mounted a device such as a propeller 16 for circulating the liquid in the bath and this may be driven either directly or indirectly. Behind the down pipe 'l1 vthere is provided a ilter 18 which is mounted in the extension 15 so as'to be interchangeable.
